FUEL-SAVING DEVICE FOR EXPLOSION-ENGINES.

To all whom it may concern:

. Be it known that I, WALLACE L. BELL, a citizen of the United States of America, residing at Athens, in the county of Clarke, State of Georgia, have invented certain Improvements in FueLSaving Devices for Explosion-Engines, of which the following is a description, reference being had to the accompanying drawings, forming a part thereof.

The object of the invention is to provide a simple, inexpensive and efficient attachment "in fu l lin 1,

v vention, there is Further objects and advantages of the infor explosive engines designed to economize the use of fuel by providing for the supply to the intake manifold a maxiinum amount of air when the engine is running under a light load, and a minimum amount when the en us is runningunder a heavy load, the contro of the amount of air adinitted to the mixture being automatic and dependent upon. the stroke of the engine and the stress or tension of the suction produced thereby.

the operative position to an'inta e manifold.

Fi 2 is a longitudinal sectional vie w of the attac out with the valve shown in its normal position as when not subjected to cylinder suction.

F 3 is, view similar to Fig. 2' wherein, the valve is shown in its fully seated position at the-discharge end of the attachment, and in dotted lines in a restrained position due to the arrangement of an adjustable stop or limiting meat .s.

In the illustrated embodiment of the in rovided :1 preferably tubular run-way 10 avi an inlet 1- 1, formed for exam la in aremova le lug 12 and fitted with a va ve seat 13 designe to rec aive a ball valve 14. At its outlet or dischar; e end the runway is pfiovided with a threuled nipple 15 or other nieans for attachment to a mamfold 16 and also with a seat 17 for the afore Q5 valve,'wh er'eby, unless 0th; rwise pre- Speclflcation of Letters Patent.

vented, a suflicientlystrong suction in the intake manifold of the engine will result in drawing the ball valve from the position illustrated in Fig. 2 to that illustrated in full I With the apparatus herein describedand involving the use of the attachment incom neotion with the intake manifold of the engine, it is possible when the en e is running under a light load to permit the influx of a relatively large percentage of air through the attachment due to the unseating of thevalve from the inlet end ofthe run-way to reduce the richness of the mixture b preventing the full suction of the cylin ers to operate through the carbureter. On' the other hand, when the engine is travelin un-- der a heavy stress or'load, the valve is a apted to be drawn to the discharge end of the run-way so as to reduce or cut ofl the'su-pply of air through'that source and cause t e cylinders through their rectly or more directly through the car bureter. V

Under these conditions the carburetor may give the maximum efliciency ture under the maximum estimated load-or suction to act, *di-* stress, the economizer bein depended upon to cut down the richness o the mixture under a light load by reducin the eifect of the suction stroke of the cylin ers upon the carburetor.

However, it has also been found desirable in practice and more es ecially in adapting the attachment to di erent engines an where different conditions of operation are encountered, to provide for a graduation of the, air inlet to the manifold, or discharge into the manifold from the run-way under the maximum or most severe stress or tension due to the stroke of the engine, and to this end, a limiting devlce 15 provided for the valve 14 in the path of its a preach to the discharge s at 17 thus afi'or mg means *to break thesution when the valve is seated .at

2. A fuel economizing attachment for use in connection with the intake manifold of an explosion engine, the same consisting of a tube having angularly disposed arms forming a continuous valve run-way, depressed toward its inlet end, valve seats at the inlet and outlet ends of said run-way, and a gravity actuated valve mounted in the run-way.

An auxiliary air supply device for direct exposure to the suction of an explosive engine, having a tube downwardly directed on a curved line from its outlet end, and a valve operat ng in the bore thereof, said tube being rovided near its discharge. end with 'an out et-scat for the reception of the valve.
